Figure 7

Top panels: $p_{\mathrm{T,ch\,jet}}$-differential cross section of charm jets tagged with $\mathrm{D^{0}}$ mesons for $R=0.2$ (circles, scaled by 0.1), $0.4$ (squares) and $0.6$ (crosses, scaled by 10) in pp collisions at $\sqrt{s}$ = 13 TeV (left) and $\sqrt{s}$ = 5.02 TeV (right) compared to PYTHIA 8 HardQCD Monash 2013 (dash-dotted lines), PYTHIA 8 SoftQCD Mode 2 (dashed lines), and POWHEG hvq + PYTHIA 8 (open circles) predictions. The shaded bands indicate the systematic uncertainty on the data cross section while open boxes represent the theoretical uncertainties on the POWHEG predictions. Bottom panels: ratios of MC predictions to the data for $R=0.2$, $0.4$ and $0.6$.
